WinterLynn nn Winnie--- I like!KatherineJessamine nn Kit----Prefer Catherine with a C as I love Cate better with a C but a nice name either wayWillaMay ----I like this, underused differnt, I think the little Willas of the world will spend a lot of time explaining they are not WIllowAdela- Love! We were tossing around Adeline for a while and said we would call her Della. Violet -- i think this name is pretty in theory but i see VIOLENT everytime i read it.Kenna (really like this name but DH's sister's name is Kendra and we do not want it to be an honor name lol.)----Not a fan

Winter is a great, modern name. However, the recent attention/buzz it seems to be receiving coupled with its first appearance last year on the Top 1000 might spell the makings of a fad, so that's something to be mindful of if you worry about that.Willa is lovely too - vintage feminine without being frilly. I love all the W-names, really: Winter, Winifred, Willa, Willow, Winslow, Wendy, Wilhelmina...

Violet is a classic and Nameberry favorite. Of all the names you listed, this would probably be the least controversial. That's not necessarily a good reason to choose a name, but it doesn't hurt.

Not as fond of Kenna, but I think I'm just tired of the K-name trend in general, which in coming decades will be timestamped as very particular to the late 90s/early 2000s. But if it's a name that has meaning for you, go for it! :-)
And Katherine isn't trendy, so it escapes that association (although I prefer Catherine); I like it, but as far as classic/vintage names go, I prefer Willa and Violet. And Winter is just cool.
